According to the Pinal County Sheriff's Office, Delcid called police when he realized what had happened. He told investigators that he'd unloaded the .38 caliber pistol just prior to the accident and thought there were no bullets remaining in the gun.

Instead, a lone bullet struck his girlfriend in the chest. The victim, 19-year-old Dina Dicochea, was pronounced dead at the scene, KSAZ reported.

"This case is a tragic reminder of how quickly a life can be taken by those who handle firearms irresponsibly," said Sheriff Paul Babeu told ABC 15.

"I wish to God she had had an m-4 in her office, locked up so when she heard gunfire, she pulls it out ... and takes him out and takes his head off before he can kill those precious kids," Gohmert said of slain principal Dawn Hochsprung on <a href="http://www.huffingtonpost.com/2012/12/16/louie-gohmert-guns_n_2311379.html"><em>Fox News Sunday</em></a>. He argued that shooters often choose schools because they know people will be unarmed.
